광표백으로 유기되는 복굴절을 이용한 전기광학 폴리머 광도파로 편광기의 제작 Fabrication of integrated optical waveguide polarizer by utilizing the birefringence induced by photobleaching in an electro-optic polymer

A polymeric waveguide TE-pass polarier operating at wavelengths around 1.55㎛ is realized by utilizing the birefringence induced by photoleaching at room temperature. To implement the polarizer, the photobleached waveguide supporting only TE mode is integrated in the middle of the etched rib waveguide that supports TE and TM modes. It has a simple structure and requires no high temperature process like poling. The measured polarization extinction ratio is about 21dB and the estimted excess loss is about 0.4dB.
